Rust Build Command

Fix Rust build, clippy, and dependency errors: $ARGUMENTS

Your Task

  1. Run cargo check: cargo check 2>&1
  2. Run cargo clippy: cargo clippy -- -D warnings 2>&1
  3. Fix errors one at a time
  4. Verify fixes don't introduce new errors

Common Rust Errors

Borrow Checker

cannot borrow `x` as mutable because it is also borrowed as immutable

Fix: Restructure to end immutable borrow first; clone only if justified

Type Mismatch

mismatched types: expected `T`, found `U`

Fix: Add .into(), as, or explicit type conversion

Missing Import

unresolved import `crate::module`

Fix: Fix the use path or declare the module (add Cargo.toml deps only for external crates)

Lifetime Errors

does not live long enough

Fix: Use owned type or add lifetime annotation

Trait Not Implemented

the trait `X` is not implemented for `Y`

Fix: Add #[derive(Trait)] or implement manually

Fix Order

  1. Build errors - Code must compile
  2. Clippy warnings - Fix suspicious constructs
  3. Formatting - cargo fmt compliance

Build Commands

bash
cargo check 2>&1
cargo clippy -- -D warnings 2>&1
cargo fmt --check 2>&1
cargo tree --duplicates
cargo test

Verification

After fixes:

bash
cargo check                  # Should succeed
cargo clippy -- -D warnings  # No warnings allowed
cargo fmt --check            # Formatting should pass
cargo test                   # Tests should pass

IMPORTANT: Fix errors only. No refactoring, no improvements. Get the build green with minimal changes.
